Kylie Jenner Is 'Excited' for Motherhood, But Does 'Have Moments of Being Nervous' (Exclusive)

A source close to the Kardashian-Jenner family tells ET that the 20-year-old reality star is "excited to be a mother," but "has had her moments of being nervous."

However, Kylie has quite the support group! "She knows she has the best teachers to guide her through being a great mother, her own mother [Kris Jenner] and sisters."

For now, the source tells ET, "Kylie has been taking time out of the spotlight to prepare for her new life as a mother." The source adds that the mom-to-be has "been enjoying shopping for furniture and clothes for the nursery."

"I've gotten to the point... I'm like, 'OK, shut the f**k up and take your own advice,'" the 33-year-old reality star quipped. "Like, I love Kourtney [Kardashian], but... I'm going to figure it all out, I promise you. We're all going to learn. So some advice is great, but it's also not what you say, it's how you say it."
